Cross build support for known archs (with Qemu support) at live-build 3

Currently live-build 3 can only support native builds (native bootstrap) while generating a rootfs.

This blueprint is to cover the development to add official support for cross build, when producing rootfs for known archs (ones officially supported by Qemu). This will help users to easily create their own images without the need of using an ARM board.

Whiteboard

Headline: live-build 3 is now able to cross build (bootstrap) images to a known arch (Qemu compatible).
Acceptance: Call live-build 3 on an x86 host, generating one Ubuntu LEB rootfs that works the same way as the native-generated images.
